Well, I've finally managed to beat "real life" into a modicum of  
submission and managed enough time to compile a new version of Balsa.   
Hooray!  At least this fix works for me - I have another application  
where the bugs I experience seem to change every time I recompile, even  
from exactly the same source.  I've got gremlins in my system, but at  
least they are staying clear of Balsa for now.  :-)

Thanks for following up on this.
